IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Letters Patent No. 164,243, dated June 8, 1875; application filed May 7, 1875.

To all whom lit may concern:

Be it known that we, @ARMI H. VILLIAMs and WALTER W. AnLPoRT, of the city of Chicago, county of Cook and State of Illinois, have invented new and useful Improvements in Brick-Machines, of which the following is full description, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation Fig. 2, a flat view ofthe cam cylinder surface; Fig. 3, a side elevation, with a portion broken away; Figs. 4, 5, and 6, details.

The object of this invention is to improve the construction and operation of brick-inachines and its nature Consists in an improved mode of operating the plunger or plungers, and in certain improvements in the mold-followers, and arrangement for movin g the molds,

as hereinafter more fully described.

In the drawings, A represents any suitable or ordinary pug-mill; B, the secondary frame, in which ythe followers areplaced and operate; C, the base or supporting frame D, the main o1'I cam cylinder; E, the revolving mold or former; F, the cylinder beneath the mold for operating the followers; Gr, the bracket or bearing for the mold; H, the casing in which the plunger is operated I, the plunger; J, the tooth or cog-arms for operating the plunger; K, the coupling-arms; L L', the shafts or rods connected with the couplingrods, and by means of which the plunger is operated; M, the casing or guide-bars for keeping the rods L L' in position; N, the brackets or frame to which the arms J are pivoted; O, the opening or openings in the secondary frame B, into which the mold enters; P, the main shaft; Q, the toothed arm for rotating the molds; a, the roller or rollers for supporting the inner edge of the mold; b, the follower; c,tl1e arms of the follower; d, the knives or cutters in the mold; c j', the cam grooves in the cylinder D g, the coupling-nuts.

rlhe pug-mill A is made in any of the wellknown suitable forms, and is provided with the usual blades, and at the bottom with a curved plate or wiper, arranged to press the clay through a suitable opening out under the plunger. The main shaft P of the pug-mill passes through the frameB and the base-frame,

and is supported ou a suitable step or bearing beneath in the frame B. The arm Q is attached to the shaft P on a line with the gear or teeth on the mold or former E, and is arranged to engage with the teeth on the mold when the plunger is elevated or partly elevated, and has sufficient teeth to carry the former one step, and bring a fresh mold under the plunger.

In machines of large capacity the same mold or former E is attached to each of the four sides of the machine, and they are all rotated by the single arm Q.

In order to support the mold E under heavy pressure, the inner edge is supported upon two adjustable anti-friction rollers, a. These rollers are placed on each side of the plunger, and are made adjustable by slotting the bea-ring-blocks, so that they can be raised or lowered and fastened in position, or by a screw working from beneath, so that as the parts become worn they can be readjusted, and hold the mold up against the plunger-case H.

rlhe plunger is operated by toothed cams or levers J, the teeth of which engage with cor# responding teeth onv the upper end of the plunger I, as shown, and the 4teeth on the plunger are crowned over to correspond with the circle of the movement of the cams J, so that when the greatest pressure is needed the cams are acting with the greatestleverage.

The levers J at their outer ends are connected with and operated by coupling-arms K, which, at their lower ends, are attached to sliding rods L L by right and left hand coupling-nuts g, so as to adjust them to proper lengths or positions. rlhese rods L are arranged to operate in unison, the rod L being operated by a pin and roller in the cam-groove f, and supported in position by the guideframe M, and the rod L is operated by a pin and roller projecting into the cam-groove e, and is held in position by a similar guideframe, M, which is made shorter than the guide-frame of the rod L. These grooves c and f are so arranged as to work in unison on each of the four sides of the machine, and

also to operate alternately, so as to equalize provided with a pin operated by a ange on the circular plate F in the usual manner, and for makin g brick they may be made plain and solid at the top, if desired, but for pressing peat, or other material containing surplus water, they are provided with perforated caps b, which are supported on the follower by a central ridge, as shown at Fig. 6, with as many cross-ridges as may be necessary to give a firm support. The cutting away `of the,fol lower beneath the plate permits the water to flow down through the plate and down at the sides of the follower, which may be provided with grooves at the sides to facilitate the further discharge of the water, if desired.

This device will be found useful in pressing peat, and when used. as a peat-machine a part or all of the molds are or may be provided with cross-knives cl, which, as the material is pressed in, will divide it into smaller bricks or sections, which will obviate the necessity of breaking the blocks for use as fuel. When these knives are inserted grooves will be made in the follower so as to lift the sections without disturbing the knives.

The basename C may be made in any suitable manner, and power may be applied to the machine by means of the shaft X, provided with suitable gearing to engage with the gearing on the cylinder D, as shown, or by an)r other suitable means.

In the operation of the machine considera-` ble more clay passes under theplunger than is required to form a brick. Curved or inclined holes are made in the lower end of the plunger, so as to pass the surplus material back into the pug-mill. This disposition of the surplus material causes a movement through the clay, which e'ectually expels the air, and forms a perfect brick with less pressure than would otherwise be required.

What we claim as new is as follows:
